PROPULSION MEANS FOR VESSELS.

T 0 all whom it may concern:

Be it known that I, Or'ro J. PETERSON, a citizen of the United States,residing at Egli, in the county of I-Iarney and State of Oregon, haveinvented certain new and useful Improvements in Propulsion Means forVessels, of which the following is a specification, reference being hadto the accompanying drawings.

This invention relates to new and useful improvements in propulsionmeans for vessels and the like and has for its object to provide animproved means for expelling the water from the stern of the vessel bymeans of centrifugal force.

A further object of the invention resides in providing a bowl-shapeddeflector or the like formed at the stern against which the water isforced as the same is expelled.

A still further object of the invention resides in the provision of adevice which is extremely simple and durable in construction,inexpensive to manufacture and one which will be very efficient anduseful in operation.

l/Vith these and other objects in view, the invention consists in thenovel features of construction, combination and arrangement of parts aswill be hereinafter referred to and more particularly pointed out in thespecification and claims.

In the accompanying drawing forming a part of this application, Figure 1is a fragmentary horizontal section through the hull of a ship showingmy improved propulsion means applied thereto; and Fig; 2 is a. rear endelevation of the same. I

In describing my invention, I shall refer to the drawing in whichsimilar reference characters designate corresponding parts throughoutthe several views and in which 1 indicates the hull of a vessel or shipof any desired type whatsoever, through which extends the longitudinalshaft 2 which has a pulley or the like 3 mounted thereon. This pulleyconnects through the medium of a driving belt or other connecting means4: to an additional pulley 5 carried on the drive shaft of an engine 6.While this particular operating means is shown and described for therotation of the shaft 2, it will be appreciated that any other form ofoperating means may be used, if desired.

Mounted in the stern of the hull 1, is a bowl-shaped member 7 the samefacing outwardly and having a portion thereof pro- Specification ofLetters Patent.

Serial No. 729/81.

jecting-within the space incloscd by the hull and the shaft 2, whichextends centrally through the hull, has the rear end thereof extendingthrough the central portion of this bowl-shaped member to projectslightly therewithin. his latter end of the shaft 2 is threaded, asshown at 8 to be engaged with a circular head member or the like 9. Thishead member consists of a substantial collar or sleeve portion 10 havingthe forward end closed by a wall, with which is engaged the threaded endof the shaft 2, and a plurality of arcuate tubular arms 11 radiate fromthis collar portion. Portions of these members 11 form continuations ofthe rear wall of the member 9 and the bores of these radial tubular arms11 communicate with the inclosure defined by the collar 10 through themedium of the openings 12. It might also be here stated that the wall atthis forward end of the sleeve or collar portion 10 is designedconcave-convex, the curvature thereof being coincident with thecurvature of the inner wall of the bowl-like member 7 and as the tubularmembers 11 have portions thereof which are continuations of this rearwall, these tubular members are, in themselves, somewhat arcuatelydesigned. From this construction described, it will be appreciated thatthis head member with the radial arcuate arms thereon will form asubstantial propeller in itself. In the operation thereof, however, thewater will be entered in the head member through the collar portion 10and as the same is caused to rotate through the rotation of the shaft 2,this water will be expelled through the radial arms 11 to contact withthe walls of the bowl-shaped member 7. Through the rotation of this headmember and the. simultaneous expulsion of the water therefrom againstthe bowl-shaped member, it will'be appreciated that the hull and partscarried thereby may be readily propelled in a body of water.

From the foregoing description of the construction of my improvedpropulsion means, the operation thereof will be readily understood andit will be seen that I have provided a simple, inexpensive and eflicientmeans for carrying out the objects of the invention.

While I have particularly described the elements best adapted to performthe functions set forth, it is obvious that various changes in form,proportion and in the minor details of construction may be resorted towithout departing from the spirit or sacrificing any of the principlesof the invention.

Having thus described this invention, what I claim is 1. In a propulsionmeans for vessels, the combination with a hull and bowl-like membermounted in the stern thereof, said bowllike member facing outwardly; ofa shaft extending longitudinally of the hull and projecting through thecentral portion of said bowl-like member, a head member of sleeve-likedesign having one end thereof closed and removably engaged with theprojecting end of said shaft, a plurality of substantially radial andcurved tubular arms formed on said head member, the bores of which havecommunication with the interior of said head, and means to rotate saidshaft.

2. In a propulsion means for vessels, the combination with a hull, and abowl-like member mounted in the stern thereof, said bowl-like memberfacing outwardly therefrom; of a shaft extending longitudinally of thehull and projecting through the central portion of said bowl-likemember, a sleeve-like head member having a concavowith the rear end ofsaid shaft, the curvature of said forward wall being designed coincidentto the curvature of the wall of said bowl-like member, a plurality ofsubstantially radial and rearwardly curved tubular arms formed on saidhead member, the bores of said tubular members having communication withthe interior of said sleeve-like head member and said members alsohaving portions thereof forming continuations of the forward Wall ofsaid head member, and means to rotate said shaft and head member carriedthereon.

In testimony whereof I hereunto affix my signature in the presence oftwo Witnesses.
